First, allow the mostly clueless to try and answer :)

I think you're not handling the deletion of the row correctly. Here's
some code I've got which deletes a row:

        msg = wx.grid.GridTableMessage(self, wx.grid.GRIDTABLE_NOTIFY_ROWS_DELETED, self.dbnames.index(name), 1)
		self.GetView().ProcessTableMessage(msg)
	
I have an array of dbnames in my custom table. I'm trying to delete the
row which contains the "name" variable. So, make a message, specifying
which table it comes from (self), what is being done
(wx.grid.GRIDTABLE_NOTIFY_ROWS_DELETED), the index of the row being
deleted (self.dbnames.index(name)), and how many rows are being deleted
(1). After that, make sure that the grid itself processes the update.

I hope this is of some use!
